I run Ubuntu Budgie 21.10. Since two days before turning off display after idle went well (DPMS mode).
Since yesterday turning off display doesn't work anymore. The display goes black for a second but then it comes back again. However, the screen is frozen (no repainting) as long as I use the desktop, e.g. keyboard, mouse movements. I guess that this is related to a recent update of libmutter. There has been an update (see /var/log/apt/history.log): Start-Date: 2021-11-17 04:50:38 Commandline: /usr/bin/apt-get -o quiet=1 dist-upgrade -y -o APT::Get::Show-Upgraded=true Upgrade: libmutter-8-0:amd64 (40.5-1ubuntu2, 40.5-1ubuntu3~21.10.1), mutter-common:amd64 (40.5-1ubuntu2, 40.5-1ubuntu3~21.10.1), accountsservice:amd64 (0.6.55-0ubuntu14, 0.6.55-0ubuntu14.1), netplan.io:amd64 (0.103-0ubuntu7, 0.103-0ubuntu7.1), libaccountsservice0:amd64 (0.6.55-0ubuntu14, 0.6.55-0ubuntu14.1), libnetplan0:amd64 (0.103-0ubuntu7, 0.103-0ubuntu7.1) End-Date: 2021-11-17 04:50:41 Package: mutter-common Version: 40.5-1ubuntu3~21.10.1 Package: libmutter-8-0 Version: 40.5-1ubuntu3~21.10.1 Kernel is: Linux xxx 5.13.0-21-generic #21-Ubuntu SMP Tue Oct 19 08:59:28 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Mesa is: OpenGL renderer string: Mesa Intel(R) Iris(R) Plus Graphics 655 (CFL GT3) OpenGL core profile version string: 4.6 (Core Profile) Mesa 21.2.2 OpenGL version string: 4.6 (Compatibility Profile) Mesa 21.2.2 OpenGL ES profile version string: OpenGL ES 3.2 Mesa 21.2.2 System is also an Intel NUC (NUC8I3) but I don't think that it is limited to this setup. I had a simular problem earlier with Ubuntu 21.04 and Kodi media center (see also https://github.com/xbmc/xbmc/issues/19479). I have closed this issue a few days before since I though it was finally solved. This time there is no output when I watch the events by using xev. ** Bug watch added: github.com/xbmc/xbmc/issues #19479 https://github.com/xbmc/xbmc/issues/19479 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1949262 Title: Power Savings doesn't turn monitor off on NUC8i5INH To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1949262/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
